The designated space on the flight progress strip for the Mode 3/A beacon code is located in position 27. This is important as the Mode 3/A beacon code, also known as the transponder code, is essential for identifying aircraft on radar displays. Each position on the flight progress strip has a specific purpose, and understanding where certain information is recorded is critical for efficient air traffic control operations.

Position 27 is specifically allocated for the beacon code so controllers can quickly reference and confirm the code assigned to each aircraft. This helps in ensuring that the correct transponder is set, which is vital for proper tracking and communication with the aircraft. Knowing the precise layout of the flight progress strip allows controllers to efficiently manage their workload and respond to any changes in flight operations.
